Hibiscus plant named “James Fleming”

ABSTRACT

A new and distinct cultivar of winter hardy  Hibiscus  plant named ‘James Fleming’ is the result of a unique hybridization. This new and distinct cultivar is characterized primarily to its novelty by, its extreme cold hardiness to Zone 4, large, thick-textured, light pink flowers and its ‘maple-shaped’ leaves with a purple coloration, compact ness of about 3 feet, its vigorous and uniform growth habit and its floriferous nature from midsummer until frost.

BACKGROUND OF THE NEW PLANT

The new plant of this invention is the result of a unique hybridization, with the breeding achievement being evidenced in the outstanding combination of characteristics exhibited by this new and distinct Hibiscus plant, which include:

-   -   (a) Refined, 3-5 lobed ‘maple-shaped’ leaves with a purple color         and relatively smooth margins which combined compliments the         landscape;     -   (b) Medium-sized flowers that are outstanding for their bright         luminescent pink colored, thick textured petals;     -   (c) The plant being very floriferous with flowers that stay open         for at least one full day, sometimes up to 3 days;     -   (d) The plant being small to medium- sized but vigorous with         compact and uniform breaking action which gives it unique         landscape utility; and     -   (e) The plant being so hardy that it can consistently withstand         winter temperatures of at least −30 degrees Fahrenheit.

SUMMARY OF THE INVENTION

‘James Fleming’ was the result of a 40-year breeding program. Its ancestry includes Hibiscus moscheutos and Hibiscus coccineus. More specifically, the plant resulted from multiple crossings with an unnamed, Fleming-bred Hibiscus moscheutos (non patented) and an unnamed Fleming-bred Hibiscus coccineus (non patented). The seedling which most nearly met all of the above standards was selected.

This new plant first bloomed in the summer of 1996 and was selected by David Fleming and Gretchen Zwetzig on David Fleming's property located at 8101 S. 14th St. Lincoln, Nebr. 68516. Asexual propagation of the plant by cuttings and root division in Lincoln, Nebr. has shown that the unique and distinguishing features of the plant are faithfully transmitted from generation to generation and appear to be fixed.

Since its origin, the plant has bloomed from midsummer until frost, while exhibiting the aforementioned distinctive characteristics. This hardy Hibiscus plant greatly contributes to the market with its, sheer beauty and utter refinement, its compact growth habit, its enhanced resistance to disease and insects, its stability through extremes in rain and drought, and its extreme hardiness.

BRIEF DESCRIPTION OF THE DRAWINGS

The flower and foliage of the cultivar are shown at 2½ years in the attached drawing. More specifically, the drawing is a close-up of the flower and the leaf.

The colors are as true as is reasonably possible to attain in photographic illustrations of this type. The colors illustrated may be slightly off due to light reflectance.

DESCRIPTION OF THE NEW PLANT

What follows is a detailed description of the new cultivar. The specific color descriptions are in accordance with The Royal Horticultural Society Colour Chart, while general color recitations are consistent with ordinary American terminology.

‘James Fleming’ has not been observed under all possible environmental conditions. It is to be understood that the phenotype may vary significantly with variations in the environment such as temperature, light intensity, humidity, and day length without, however any difference in genotype of the plant. The following botanical characteristics and observations are gathered from the plant when grown in Lincoln, Nebr. (USDA Zone 4).
